Hangzhou xiaoshan fire subsequent fragile caigang houses have holes

Make the most beautiful firefighters "YinJin good three fire fighters heroic sacrifice of hangzhou xiaoshan fire happens, the personage inside course of study points out, in recent years" popular "choi steel building in the fire because of high temperature softening and easily cause the overall collapse, not only greatly increase the difficulty of fire suppression, and a serious threat to the trapped and fire personnel's life safety -- -

Increase the fire danger threat under siege life

Zhejiang fire corps reported xiaoshan fire details show, xiaoshan youcheng mechanic co., LTD. The point is 2 steel structure workshop warehouse, also is our common colored steel board. In the three martyrs before sacrifice, the fire happens inside flashover. Three martyrs body, also in a collapsed under the frame of the find. "Steel in the fire temperature reached a certain point of time, will occur softening, its compressive resistance will suddenly fall in the whole building collapsed, thus greatly increased into fire rescue in the firefighters risk factor. Shijiazhuang city public security fire control team ZhouXueTong ninth squadron instructor in an interview with the author said. Shijiazhuang city public security fire control team vice captain LiXinBao said: "many trapped personnel is not be burned to death, but by gas poisoning. Some color steel plate internal filling of polystyrene foam plastic combustion will produce virulent, the men will be a large number of suction in a short time died."

As we have learned, since the turn of the century, due to the construction period is short, the cost is low, choi steel building in enterprise workshop, warehouse and retail store's construction is "popular".

Gb has holes "core" is very fragile

Compared with colored steel plate easy softening temperature of the "natural defect", at present the color steel production in the existing "human hidden danger" more worthy of attention. "With pure steel structure is different, choi steel outer layer is the steel plate, the inner is packing. Hebei university of technology materials science and engineering college secretary of the party committee CuiChunXiang professor told the author, choi steel inner packing including polystyrene foam plastic, rigid polyurethane, rock wool, slag cotton material. In order to reduce cost, currently on the market choi steel ago two material for packing, but these two kinds of material in high temperature easy decomposition softening, thus accelerating choi steel building in the fire, equal to the whole collapse for increased choi steel building fire hidden danger.

CuiChunXiang professor says, the current national standard color steel plate only foreign layer steel plate and steel belt, the rules for internal packing material and fire resistance but did not make clear a regulation, make enterprise has a loophole, lead to internal packing material is multifarious, flame retardant material also are often left out production enterprise.

Life is priceless mo anxious to get things on the cheap

ZhouXueTong the squadron of jurisdiction, in north China's largest small commodity collection and distribution center - shijiazhuang NaSanTiao market. This merchant, the passenger capacity big, once fire, may cause significant casualties and property losses. And some merchants privately built choi steel shops and warehouses, it is let ZhouXueTong and comrades-in-arms headache at the fire hazard. They insisted that merchants to tear down these choi steel buildings, but it has met with their strong block.

And some enterprise "bait-and-switch" behavior, increase the difficulty of the supervision of the fire department. "According to fire regulations, warehouse, workshop this kind of level 3 building it is strictly prohibited to use flammable materials. But choi steel internal packing into combustible materials and non-combustible material two kinds, so the color steel plate itself is not a complete ban the use of internal packing for rock wool. Can't wait combustible material, is allowed to use. But due to internal filling material for polystyrene foam plastic choi steel price is cheap, so are more users favor. Some enterprises in the driven, the workshop in examination and approval acceptance with is not combustible packing color steel plate, the fire department acceptance, then secretly with combustible packing color steel plate. This case is not rare. The ruthless, life is priceless, don't let benefit blinded, but lost the most precious life." LiXinBao said.
